Patent number: 8877284Abstract: A method for making a flexible and clear plastics material article of manufacture having a low electric surface resistance, starting from a plastics material having a higher electric surface resistance, in which the electric surface conductivity of the starting article of manufacture is modified by partially including, into at least a portion of the outer surface of the article, carbon nanotubes. With respect to conventional methods, the inventive method allows to modify the starting plastics material electric surface resistance so as to lower it to values smaller than 102 k?/sq, even starting from articles having a higher resistance of the order of 1013 k?/sq, while preserving the starting clearness and flexibility thereof.Type: GrantFiled: May 4, 2010Date of Patent: November 4, 2014Assignee: IVG Colbachini S.p.A.Inventors: Gabriele Marcolongo, Moreno Meneghetti

Patent number: 8083981Abstract: A flexible tube comprises a tubular body made of a curable flexible material, having at least an elbow shape, and made by a double curing, the first on a straight mandrel, and the second on a shaped cylindric core, to provide the tube with a desired configuration. With respect to the conventional art in this field, the invention provides the advantage that the shaped tube made thereby is directly provided, at the end portion thereof, with the required fittings, without the need of performing auxiliary processing steps to clamp the fittings.Type: GrantFiled: October 10, 2007Date of Patent: December 27, 2011Assignee: IVG Colbachini S.p.A.Inventor: Giuseppe Aldinio Colbachini
